Abstract: The continuous automatic CNC lathe processing completed all turning process, should pay attention to choose rational cutting parameter, cutting tool, the reasonable choice selecting fixture, determine the processing line, processing route and machining allowance, fixture installation points, etc. And from change knife complement ensure dimensional accuracy, semi-finishing elimination of the influence of screw clearance to ensure dimensional accuracy was studied considering control dimension precision techniques.

Abstract: According to driving requirements of single-chamber and single-vibrator piezoelectric pump, a program-controlled driving power supply is designed. The power supply first utilizes D/A converter and voltage-controlled oscillator to generate sine signal with adjustable frequency, then it changes the amplitude of signal by T-type resistor network. At last, it utilizes high-voltage amplifier and power amplifier to obtain a high voltage and a large current to realize drive of piezoelectric pump. Output voltage and frequency of power supply can be adjusted under control of program. Prototype of driving power supply is manufactured and its output performance is test. Experimental results show that, in power supply, waveform of the sine signal is satisfying, range of output voltage is 0-170V and range of output frequency is 5-600Hz. Power supply designed meets the driving requirements of piezoelectric pump, and also has merits of small size, light weight and low cost.

Abstract: Hydraulic excavator is the important construction machinery. In order to realize the excavator robot intelligent control system from the research on operator's comfort and maneuverability, the paper introduces the establishment of the bucket action model. And at the base of the model, the hardware and software are designed. The experiment shows that the system has the advantage of stability, reliability and strong anti-interference ability.

Abstract: Based on the excellent characteristics of the cloud model on the conversion process between irregular knowledge of qualitative and quantitative representation, judgment set with cloud model was established, a comprehensive state assessment method of the hydraulic subsystem of the launch site was proposed. Finally, put weighted deviation degree into judging cloud generator to acquire the comprehensive state.

Abstract: The application of industrial robots in modern industry is very common, it not only can be used for manufacturing, and assembly areas can also be used. Its development and progress, especially in the development of intelligent robot can be considered to reflect a country's scientific and technological strength and technical level. In this paper, a detailed study of the control structure of the robot, on this basis, the design of a robot control system architecture, hardware and software design. In last with VC + +6.0 developed a control interface for a robot control system.

Abstract: In the environment of harsh weather or obstacles, the corresponding monitoring department can't achieve remote control and acquire the accurate location of the unmanned aerial vehicle (UAV). According to the existing problem this paper designs a logical control module based on single chip microcomputer (SCM) C8051F040 and UAV real-time tracking system which is positioned by GPS. In this design, through the analysis and extraction of the GPS data, then transmit these data to the host computer through the USB interface with high speed, the unmanned aerial vehicle (UAV) flight vector position such as longitude and altitude information will be displayed by the host computer. After tested for several times, this vector pursuit system can acquire the accurate position of the unmanned aerial vehicle (UAV) and the corresponding flight path within 20 km. To some extent, it provides an effective guarantee for the remote control and monitoring department.

Abstract: A server architecture composed of multiple embedded boards connected by serial RapidIO bus is proposed, and a solution of boot over serial RapidIO is provided. This solution can allow the master board to dynamically discover configure boot and release the slave boards according to service demands and provides all images to the slave boards. This architecture is reliable scalable and low power consumption.
